UV+UF water purifiers are made from the combination of Ultraviolet and Ultra-filtration purification technologies.
India faces serious challenges in addressing safe drinking water requirements for a long time. Poor quality of water supplied by civic authorities remains one of the biggest challenges in the country. Diarrhea – a waterborne disease – causes 13% deaths among children below 5 years of age in India, which is caused due to germs.
So, UV+UF technology is the pressing need for water purification.
What is UV+UF Water Purifier?
The UV+UF method incorporates both Ultraviolet and Ultra-filtration technologies for the purification purpose.
In this technology, water is purified in a multi-stage cleaning process in which bacteria, virus, germs, and microorganisms are killed and then, dissolved salts and impurities in the water are removed.

How Do UV+UF Water Purifiers Work?
In the first stage, the ultraviolet light with an optimum level of intensity is passed on to the water to kill harmful bacteria and other microbes by altering their DNA. The UV filters can remove pesticides and pathogens by up to 99%.

In the next stage, the water goes through the ultra-filtration process. It is a type of membrane filtration in which hydrostatic pressure or concentration gradients are used to separate suspended solids and solutes of high molecular weight through a semi-permeable membrane. UF utilizes hollow fibers as a membrane material through which water passes through.
Though UF is not fundamentally different from RO, the only difference is the pore size of the UF membrane is larger than the RO membrane but it does not allow any bacteria, viruses, and germs to pass. It can either be used as pretreatment for reverse osmosis or as a final filtration stage for de-ionized water.
When to Use UV+UF Water Purifiers?
- The UV+UF-based water purifiers are recommended for water with a TDS level of less than 500 ppm.
- Ideal for municipal water supply.
- For water with a high concentration of biological impurities like bacteria, viruses, cysts, etc.
